PNEUMATIC TIRE.

Speccaton of Letters Patent.

Application filed March 26,

Patented Aug. 5,1913. 1912. serial No. 686,34?.

Be it known that we, RALLY EHLE and REX EHLn, citizens of the UnitedStates, residing at Council Bluffs, in the county of Pottawattamie andState of Iowa, have invented certain new and useful lmprovef ments inPneumatic Tires, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to automobile tire protectors. i

The principal object of this invention is the production of an efficienttire protector which is made up of several laminations of toughenedfabric which is treated with rubber or other adhesive material forforming a compact mass.

`With this and other objects in view this invention consists of certainnovel constructions, combinations, and arrangements of parts, as will behereinafter fully described and claimed.

ln the drawings: Figure l is a transverse sectional view of the tire.Fig. 2 is a detail perspective of a pair of sections forming theprotector means. Fig. 3 is a detail perspective of a number of theprotector cords or strands showing the manner of assembling the same inorder to form the protecting medium for the tire protector. Fig. l is anenlarged detail section of the lower end of the tire protector as isused when forming the tire.

It should be borne in mind that the present device as illustrated andhereinafter described may be formed as a portion of the tire itself asindicated in Fig. l or may be formed as an inner protector coveringplaced between the inner tube of the tire and the outer casing. In Fig.l, the tire is shown as provided with the inner protector l, as well asthe embedded covering 2 formed in the tire itself. It should beunderstood that either of the protector means l and 2 may be usedindependently of the other without departing from the spirit of theinvention, and furthermore, it

To all whom if may concern I should be understood that, especially inlight tires, the inner protector casing l is adapted to be used, and itis not necessary to use the embedded protector when a light tire isused. The inner protector l may be, and is, manufactured entirelyseparate from the tire and may be inserted within the tire of theordinary pneumatic type without affecting the construction of the same.These protector casings, both the struct-ure as shown in the embeddedprotector and the separate casing, are formed in like manner, only theinner protector is formed of lighter material than that which isembedded in the tire as will be fur-ther described in the followingspecification.

The protectors are formed from a plurality of sections which haveportions overlapping each other to form a continuous band. rilhesesections extend transversely of the tire as illust-rated in Fig. l. Eachof the sections comprises a plurality of strands of rope, cord, or othermaterial t which are coated with some adhesive substance for firmlyholding the strands in their correct parallel relation. These strandspass transversely of the tire and conform to the shape thereof, and areembedded between the folded ends 4" of the fabric covering 3, whichfolded ends constitute a pocket. Two sheets of the fabric covering 3 areemployed. The main portion of the protector fabric sheet 3 is bent backupon the inner end of the adjacent fabric sheet, thereby form ing acomplete incasement for the rope strands l as illustrated in Fig. 2.These strands 4L are stretched parallel to each other, and are coveredwith a coating of rubber or other suitable cement, as above stated, andare placed length to length, as especially illustrated in Fig. 3 therebydividing the tire protector into a number of individual protector stripswhich strips are closely fitted together to constitute a continuous bandaround the entire face of the tire. These strands 4L are of sufficientlength to accommodate the different sized tires upon which the protectoris used. will be seen by carefully considering'Fig. 2 that the ends o-fthe fabric covering 3 eX- tend in opposite directions thereby forming anellicient wrapping for the strands il, and preventing the displacementof the strands from the pocket. After one section has been formedanother exact-ly similar to that described is placed upon the lower freeend of one of the complete protector sections and has one side of thecord containing pocket abutting the side of the cord containing pocketof the next succeeding protector, thereby forming a continuous protectorband for t-he tire. From Fig. 2', it will be seen that the free ends ofthe pro- Cfr tector strips overlap each other and form a continuousband, and the fabric 8 may be formed of any desired material and mayalso be coated with an adhesive substance for facilitating the adherenceof one section of the protector strip to the other as illustrated inFig. 2.

lll/*hen the protectfu' is used as a portion of the tire itself and isembedded therein, tie process of manufacturing or en'ibedding` theprotector Within the tire is as follows The protector strips aremanufactured as above set forth and connected together as illustrated inFig'. Z and previously den scribed, in such a manner as to form acomplete circle of sections, which sections extend transversely of thecircle, said circle be` irre` formed of suflicient size to fit the tirefor which the protector is intended. This circle of sections so preparedis then placed on forni composed of one ply of fabric, to constitute aprotector. This protector is then placed upon an air bag and theninclosed by tivo steel rims. .lt is then Wrapped in cloth bands and thesaid protector so prepared is placed in a steam heater and cured orvulcanized. fit the end of this curing or vul canizing process, theprotector or casing is then removed and is complete. and ready to beplaced in the tire for use and to receive the outer coating of rubber asis usual in the ordinary case. These sections of protector strips havetheir inner ends embedded in a rubber rim 7 which extends around theside edges of the protector and this rubber rim forms an etlicientholding means for the in ner ends of the protector and prevent thefabric, as Well as the rope strands from bef coming frayed.

The protector, which may be used merely between the inner tube of thetire and the outer casing` is manufactured in the same manner as aboveset forth With the exception that the outer casing of rubber 5 isentirely eliminated from the protector l, and the free edges of theinner tube protector are beveled so as to overlap as indicated at G.rlhe free edges of this tube l may also be slightly coated with rubberor other adhesive material to prevent the fabric or strands il frombecoming1 frayed. This protector l is interposed between the tire S, andthe inner tube 9.

From the foregoing description it will be obvious that a very ei'licientand durable pro tector has been produced which will prevent the innertube from becoming punctured and Will prolong the life of the inner tubeby preventing` the saine fromblowingout, provided the outer casingshould become injured or weakened by use.

What is claimed is l. A tire of the class described comprising; aplurality of fabric sections, each of said fabric sections provided withan extending flap, the extending flap of one section overhangingl aportion of the adjacent section for constituting a pocket, a pluralityof strands positioned within said pocket, and means for securing,` theends of said sections together for forming` a complete arotector.

2. A. tire protector comprising' a plurality of overlappingsections,each section coinprising a pair of fabric sheets having` their innerends interlocking` for constituting a pocket, a plurality of parallelstrands positioned within said pocket and extending' longitudinallythereof, a portion of said fabric sections extending beyond said pocketand overlapping the next adjacent section, and means whereby saidsections are secured togather.

3. A tire protector of the class described comprising a plurality oftransversely eX tending` sections, each section made up of a pair ofsheets having interfolded ends, a plu rality of parallel strandsextending` transversely of said sheets and being placed between theinterfolded ends thereof, each sheet provided with an extending portionadapted to overlap the next adjacent sheet whereby said sheets may befirmly held together and said sheets being secured together by means ofadhesive substance.

ln testimony whereof We hereunto affix our signatures in presence oftivo Witnesses.
